step 1. Add Web service, and you must add a [System.Web.Script.Services.ScriptService] to the service class

(in webservice.asmx.cs file)

   1: /// <summary>

   2: /// Summary description for WebService1

   3: /// </summary>

   4: [WebService(Namespace = "http://tempuri.org/")]

   5: [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]

   6: [System.ComponentModel.ToolboxItem(false)]

   7: // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 

   8: [System.Web.Script.Services.ScriptService]

   9: public class WebService1 : System.Web.Services.WebService

  10: {

  11:     [WebMethod]

  12:     public string DeleteProduct(string id)

  13:     {

  14:         Thread.Sleep(800);

  15:         return "Hello World22: " + id;

  16:     }

  17: }

step 2. call webservice in aspx via jQuery

(in head of the page)

   1: <script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script>

   2: <script type="text/javascript">

   3:     $(function () {

   4:         $('a').click(function () {

   5:             deleteProduct(111);

   6:         }); // end of  $('a').click(function () {

   7:  

   8:     });     // end of $(function () {

   9:  

  10:  

  11:  

  12:     function deleteProduct(id) {

  13:         $.ajax({

  14:             type: "POST",

  15:             url: "WebService1.asmx/DeleteProduct",

  16:             data: "{id: '" + id.toString() + "'}",

  17:             contentType: "application/json; charset=utf-8",

  18:             dataType: "json",

  19:             success: function (msg) {

  20:                 AjaxSucceeded(msg);

  21:             },

  22:             error: AjaxFailed

  23:         });

  24:     }

  25:     function AjaxSucceeded(result) {

  26:         alert(result.d);

  27:     }

  28:     function AjaxFailed(result) {

  29:         alert(result.status + ' - ' + result.statusText);

  30:     }  

  31: </script>

The “EF Code-First” functionality provides a pretty nice code-centric way to work with data.

Advantage

• ·         Develop without ever having to open a designer or define an XML mapping file, and start from a class
• ·         Define your model objects by simply writing “plain old classes” with no base classes required
• ·         Use a “convention over configuration” approach that enables database persistence without explicitly configuring anything
• ·         Optionally override the convention-based persistence and use a fluent code API to fully customize the persistence mapping. columbus oh website design

Disadvantage

• Mapping entities to the database is quite complex
• There is no Model diagram

Visual Studio 2010 was originally released without HTML5 support, so does SP1 finally add support for it? Yes, to some extent. The entire HTML5 specification isn’t supported but most of the new elements and attributes are. That means you get both intellisense and validation for HTML5 with SP1.

Turn it on

After installing SP1 you have to tell Visual Studio to start using the HTML5 schema. Go to Tools -> Options, and then select Text Editor -> HTML -> Validation. You should now be able to select HTML5 or XHTML5 as the target schema.

Or if you have the HTML Source Editing toolbar enabled, you can select it in the target schema dropdown.
